Understanding how gaze differs in autistic people may help improve their lives.

People who have mutations in a gene called PHF21A tend to have a constellation of traits and conditions, including autism.

A mix of two drugs eases hypersensitivity to noise in mice missing an autism gene — offering the promise of a similar treatment for autistic people.

Autism is unusually common among people with congenital blindness, in part because the ability to see drives much of brain development.

At least one in three autistic children has significant movement difficulties, according to a large study.

Mutations in the gene CSDE1 lead to a constellation of developmental delays and conditions, including autism, according to a new study.

Mice lacking one copy of a gene called DDX3X have developmental delay and sensory, motor and behavioral problems — similar to those seen in people with a mutation in the gene.

A single seizure early in life leads to enduring behavioral problems, including diminished sociability, in mice.

A new survey suggests autism prevalence has more than doubled over nine years, but the numbers may reflect only a rise in awareness and better data collection.

Certain patterns of electrical activity in the brain may signal autism in children with tuberous sclerosis complex, a related genetic condition.
